or operate the equipment.
Indicates a potentially hazardous situation which, if not
avoided, could result in death or serious injury.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury.
WARNING
CAUTION
Warning, Caution Prohibitive Action Mandatory Action
WARNING
Turn off the power at the
switchboard before beginning
the installation.
Fire or electrical shock can result
if the power is left on.
CAUTION
Be sure that the power supply is
compatible with the voltage
rating of the equipment.
Connection of an incorrect power
supply can cause fire or damage
the equipment.
Use the proper fuse.
Use of an incorrect fuse may
damage the equipment.

OVERVIEW
The IF-2550 functions as an interface for the distribution of signal between the sensors (net sonde,
current indicator, and navigation equipment) and the display units for the sonar, fish finder, radar and
plotter.

1. MODE AND FUNCTION
The IF-2550 is a unit that integrates the functions of the current interface units IF-1001, IF-2300, IF-
2500, IF-2503, and the distributor MD-550. Functionality of each model can be activated by setting
the appropriate DIP switches. DIP switch settings are outlined in Chapter 8.
The table below shows the comparison of each mode and function.

5. MOUNTING
Precautions
This unit does not have power switch. If the IF-2550 is not connected directly to a switchboard or cir-
cuit-breaker, install an external power switch (local supply) near the IF-2550.
When selecting a mounting location, keep in mind the following points.
• Use the specified cable for connecting.
• The power cable is to be supplied locally. Refer to “Cable Fabication” of this manual.
• Observe the compass safety distances and secure the distance.
• To prevent noise from the transceiver, do not tie the unit and transceiver cable with a cable tie.
• Turn off the power switch at the switchboard before proceeding with the mounting and wiring.
• Following tools are required for mounting
• Phillips-head screw driver(M3/M4)
• Hook spanner (236-332, located on the back of the unit cover)
• Mount the unit in the direction indicated in the outline drawing.
• When you mount the unit, secure the necessary service space. If service space is not secured,
maintenance cannot be done.
• The contact signal has a logical setting for both input and output. Make the settings according to
the connected device. The factory settings are all default settings.
• When you change the setting, restart the unit.

Mounting Procedure
This unit can be mounted on a desktop or bulkhead.Refer to the precautions and outline drawing at
the back of this manual when you mount the unit.
Mounting
1. Referring to the outline drawing, make four pilot holes for self-tapping screws (4x20, sup-
plied) in the mounting location.
2. Screw two self-tapping screws to the pilot holes, leaving a gap of 5mm.
3. Hang the unit on the screws and secure the unit by fastening the self-tapping screws.

Use the TTYCSLA-1, TTYCSLA-4 (Japan Industrial Standard cables) or the
equivalents.
7. WIRING
The procedure of the wiring is as follows;
1. Unfasten the four screws, then remove the cover.
NOTE: The connector sheet and hook spanner (239-332) are attached to the back of the cov-
er. Take care not to lose them.
